On the instrumental side, most inelastic neutron scattering setups are capable of molecular spectroscopic experiments perhaps TOSCA, installed at the ISIS Pulsed Neutron and Muon Facility (UK), should be mentioned as it is dedicated to such studies (ISIS 2003). Data analysis most often includes quantum chemical calculations of the vibrational density of states, which are compared to experiment (see, e.g.. Line and Kearley 2000 Fernandez-Liencres et al. 2001). 

Figure 1 Schematic representation of a typical light scattering setup.

Static light scattering (SLS) represents an old but still an extremely useful technique. In a modem scattering setup, the sample is illuminated with a laser beam, and the intensity of the scattered light is monitored as a function of the scattering angle (see Figure 18.1).

The mixing behavior of the solvent jets of ethanol, acetone, NMP, and mixtures of them are examined using the elastic light scattering setup described above and described in detail in the literature [36]. The results are used later in order to discuss the generation of tailor-made particles in the respective sections (see Figs. 24.15 and 24.16).

The TNT blast data used A substantial scatter in the experimental data on high-explosive blast can be observed which is due to differences in experimental setup. Although often referenced differently, most recommendations can be tracked back to ground burst data developed by Kingery and Pannill (1964). 

Deviating from the setup discussed earlier, the y-ray beam can also be consistently collimated by structures other than the absorber holder. If this is the entrance window of the detector, the counter should have a lead shield, and the absorber must be sufficiently large to prevent radiation from passing by. For Mossbauer scattering experiments, the same arguments have to be considered.

H2 molecular beam. The H-atom products were detected by the Rydberg tagging TOF technique using the same scheme described in the last paragraph with a rotatable MCP detector. Figure 4 shows the experimental scheme of the crossed beam setup for the 0(1D) + H2 reactive scattering studies. The scheme used for the H + D2(HD) studies is very similar to that used in the 0(1D) + H2 except that the H-atom beam source is generated from HI photodissociation rather than the 0(1D)-atom beam source from 02 photodissociation. 

In principle every scattering pattern can be recorded using the classical X-ray diffraction setup sketched in Fig. 2.2. In the detector the scattering intensity is measured in units of counts-per-second. 

Complete scattering patterns of samples with a complex single-crystal anisotropy can only be recorded in a texture setup (Chap. 9, Fig. 9.3). The samples must be rotated in order to scan the required fraction of reciprocal space.
